The shaft 76, starting to rotate in the tub 58, coated processed fluid 59. While on a course at the exit of the bath that portion of the shaft 76, which came to the plate-scraper 133 is removed from the surface of the shaft 76, so as not to dirty the upper shaft 76. However, when the rotation shaft 75 by contact of the seal on the plate 127 caught partially processing liquid is removed the seal and flows down the plate on the edge of the tub. Similarly, at the outlet during the rotation of the upper conveyor shaft 77 through a gear 157 transmits rotation in the opposite direction of movement of the lower conveyor shaft 78 through a gear 104 which engages with the gear 157. Machine is ready for operation. Take intended for processing (polishing) skin 9 and put it facedown on the table 7, moving it forward under the rotating inlet conveying rollers 75 and 76, which are on the table 7 comes into contact with electrodata 8. If this is Le pristavki contact electro - sensor 8. Thus probarbus 87 on Namazova shaft 70 remains in its original position (according to Fig. 1), i.e. from the bottom until the second end of the skin 9 of the installation zone of electrodata 8. Thus the front end of the skin, acting under the transport rollers 75 and 76, in the same initial point of entry to the thickness of the skin of the upper conveyor shaft 75 is lifted a few millimeters relative to the shaft 76. Emphasis plate-scraper 127 is also lifted together with the bracket 111, overcoming the weight of the shaft and the force on radiatia spring 50, causing the shaft 76 mechanism 128 of the second adjustment plate-scraper 133 is lifted up-regulated moment under the action of decoder springs 136, limiting the stroke of the bolt 135. From this point on in the course of transporting the shaft 76, bathing in the tub in the treated fluid 59 with a given layer thickness of the film, continues to rotate until a complete pass of the skin through namazee and transporting rollers, i.e., through transporting rollers 75 and 76. At the moment of sunset skin under the transport rollers 75 and 76 of the thin film layer is processed liquid remains on the conveyor shaft 76 under pressure. This layer of liquid short-term assures proper impregnation and not to diplomatists more thus, the surplus can be removed and remain before the point of the break. Thus, the skin is impregnated with buchtarma and pressed simultaneously transporting shaft 76 under the pressure of the transporting shaft 75 begins to act on the Cam plate 83, and then to Polish in the working area namanga shaft 70 under the presser shaft 73. While the skin on the bottom at high speeds namanga shaft 70 starts with the setting of polished brush 72. All sorts of crumbs waste 24 in migration between the two namesname shafts 70 and 71 through the lattice dies 84 fall into the storage chute 24. And the second namazee shaft 71 rotates towards the first, additionally directs the fall of the waste in the common channel. When the dressing of skin first namesnik shaft 70 leather continues on a course at the same time to keep the conveyor shafts 75 and 76 and to soak the treated liquid transporting shaft 76. In the process of skin treatment at two operations, the front end of the skin area is the installation of the first namanga shaft 70 and is supplied to the grate comb 84. The treated part of the skin clean from this point comes into contact with electrodata 85 before entering on the second brush namanga shaft 71. This electrodance 85 instantly gives the command for enabling what ectromelia 102 and the shaft 78 begins to rotate on the shafts 82 and through a chain drive 161, envelope sprocket 93 and 103 and the hub 91, rotates in the same direction to the axis 80 with Polubarinova 88 and the Cam 96 in the loop 360aboutfollowed by disconnection of the electrical locking facility (not shown). At a specified point along the front, treated skin area passes the ends of the dies 84, probarbus 88 slant "and" rises slightly above the moving skin, which is below the bevel on prabaramee 88, who has covered namazee shaft 71. The front end of the skin is not tucked second namesnik shaft rotating in the opposite direction. In the next moment, the skin continues to be processed first namesnik shaft 70, transported and promazyvaetsya transporting rollers 75 and 76. Then additionally processed is transported by the end together with Polubarinova 8 (as shaft) under the second pressure roll 74. Then on the Cam plate 86 is fed forward processed by the end of the skin under the second pair of transporting rolls 77 and 78 on the output to the storage 19. When input table 7 raw end of the skin crosses the area of installation of electrodata 8, the latter instantly gives the command to activate Electrometry 99. Electrosoft 99 merges with the sprocket 100 and with it begins to spin clockwise, the hub 90 with Polubarinova 87 and the Cam 95 is also in the loop 360aboutfollowed by disconnection of the electrical locking facility (not shown). When turning when probarbus 88 reaches the zone of installation of the lifting mechanism 139, copier 96 slant "and" it goes underneath the thrust roller 145 and upon further rotation of Polubarinova through bevel "and" simultaneously from both sides (shown with one hand raised to a predetermined height parallel to the pressure roller 74 to complete the passage of Polubarinova 88 of the installation zone of the clamping shaft 74, providing free passage of the skin over the area of the rotating brush 72 namanga shaft 71. Similarly to the specified torque when turning probarbus 87 reaches the zone of installation of the first roller 73, bevel "and" copier 95 comes underneath the support roller 142 of the lifting mechanism 138 and upon further rotation of Polubarinova 87 through bevel "and" at the same time with two sides parallel to the pressure roller 73 is raised to a predetermined height for the free passage under pressure shaft Polubarinova 87 and lying on it processed the end of the skin. Thus, when the input end of the skin will be the area of installation transporting the shafts 75 and 76 with the simultaneous impregnation and the guide plate 83, the skin has a comb 84. However, copier 95 passes the zone of installation of squeezing roller 142 and stops to interact with it, coming down with the bevel "b" why under the weight of the bracket 109 and the force of the spring 51 and the pressure roller 73 presses the original position, falling to the stop 55, and probarbus 87, completing the cycle of 360aboutautomatically shuts off electrical locking facility. In the next moment, the output of the front-treated area of skin out from under the conveyor shafts 77 and 78, probarbus 88 passes the area of installation of the clamping shaft 74, copier 96 bevel "b" is the area of installation of squeezing roller 145, which ceases to communicate with the copier. From this point the second part of the half leather processed second namesnik shaft 71, brush 72 under the force of the weight of the shaft 74 and efforts on the opening of the spring 52 to a full treatment of the skin and passing it to the storage 11 and zone setup at the output of the Chuck shafts 77 and 78. In the process of skin treatment namesname shafts 70, 71 at the output of the upper conveyor shaft 77 acts on the skin with the force of the weight, as well as efforts on the opening of the spring 53. In the final moment of processing the second skin namesnik shaft 71 at the entrance to the buffet 7 put another skin, intended for processing, after which the process arabamericans add the processing fluid 59. When washing the bath 58 last through the steering wheel 69 is lowered into the lower position. Open from the bottom (not shown), merge edges and washed the waste water. Then bath at the expense of wheel 69 rises again to its original position.The application of the proposed machine allows you to expand the technical capabilities of the process of applying the processing solution on the skin regardless of its thickness, without spoiling namasivaya shafts, and its subsequent polishing. This is achieved due to the fact that the skin, passing through namasivaya shafts of the machine, commanding the removal of residue namasivayam solution with two clanmatch shafts at the same time, by interacting scrapers, as well as through installed on the machine two polishing brush shaft.
